A revision of Tamarix specimens (Tamaricaceae) kept in the BCN herbarium of Barcelona (Spain)

2018

The taxonomy of genus Tamarix L. is notoriously controversial and many taxa are still not or wrongly identified. A huge number of tamarisk specimens are kept in the most important herbaria of Spanish universities but many labels needs a deep nomenclatural revision. The Tamarix collection in Universitat de Barcelona (BCN) is composed by 158 samples, collected in different Comunidades Autónomas de España, and corresponding to 14 taxa.

Precisiones nomenclaturales en <em>Phlomis</em> × <em>composita</em> Pau <em>(Lamiaceae)</em>

2014

Se revisan algunos aspectos relacionados con la nomenclatura de Phlomis × composita. Se tipifica el nombre P. × composita Pau (Lamiaceae) a partir de material original de Pau, recolectado por Bourgeau en 1849 y conservado en el herbario del Real Jardín Botánico de Madrid. Se rechaza la anterior propuesta de tipificación de Mateu (1986) por ser incorrecta. Se propone un nuevo estatus taxonómico para el híbrido entre P. crinita subsp. crinita y P. lychnitis, bajo el rango de notosubespecie: P. × composita nothosubsp. trullenquei (Pau) P. P. Ferrer, Guara & E. Laguna, stat. nov.

The Capparis spinosa L. group (Capparaceae) in Australia

2003

Summary The Australian form of the Capparis spinosa group, at present treated as var. nummularia (DC.) Bailey, has been studied through field and herbarium investigations. Cultivations away from the distribution range were also carried out to test the maintenance of diagnostic characters in this taxon. Based on the obtained data, coupled with phytogeographical considerations and comparisons with the variants widespread in other areas, for the Australian form the subspecific rank is here proposed. Its distribution and autecology are also discussed.

Revision of the Eduardo Reyes Prósper’s herbarium and typification of three species of charophytes (<em>Charophyceae : Characeae</em>) pr…

2019

A study of the charophytes collected by Eduardo Reyes Prósper in the period 1904–1906 and kept in the herbarium of the Royal Botanical Garden of Madrid (MA-ALGAE) is carried out. Reyes Prósper’s herbarium consists of 112 sheets, which had not been revised until now, among which are the type materials of Lamprothamnus aragonensis Reyes y Prosper, Lamprothamnus toletanus Reyes y Prosper and Tolypella giennensis Reyes y Prosper, of which their lectotypes are here designated.

THE OCCURRENCE OF SENECIO VULGARIS L. VAR. VULGARIS AND S. × HELWINGII BEGER EX HEGI (S. VULGARIS × S. VERNALIS WALDST. ET KIT.) IN ISRAEL

1994

Common Groundsel (Senecio vulgarisL. var.vulgaris(2n = 40)) is widespread in the northern hemisphere. In Israel, judging from a herbarium survey, records taken from the Israel Plant Information Center (ROTEM), and field studies, it has a restricted and widely disjunct pattern of geographical distribution, and, thus, is another example of the comparatively large group of weeds in Israel which are extremely stenochorous. The remarkable gaps in its distribution, from the Upper Golan to Mt. Carmel and to the Jerusalem area, are considered primarily to be the result of paleoclimatic changes, whereas its occurrence outside these centers of distribution is probably related to long-distance dispers…

Lectotypification of Three Linnaean Names in the GeneraPhillyreaandFraxinus(Oleaceae)

2014

Lectotypes for the Linnaean names Phillyrea angustifolia, P. media and Fraxinus ornus (Oleaceae), are designated from original material conserved in LINN (Linnaean Herbarium) and BM (George Clifford Herbarium). A specimen at BM is designated here as the second-step lectotype of the name Fraxinus ornus.

Second-step typification of Statice insignis, basionym of Limonium insigne (Plumbaginaceae)

2017

Cosson (1852: 177) described Statice insignis (Plumbaginaceae Juss.), providing a detailed description of this species, reporting several localities of provenance and indicating a pertinent gathering by the French traveler and plant collector Eugène Bourgeau: “In salsuginosis Hispaniae australioris, in regno Granatensi ad urbem Vera (E. Bourgeau, pl. Esp. n. 1442) et ad oppidula Santa-Fe et Roqueta (E. Bourgeau, 1851)”.

The comparative biology of the closely related Senecio nebrodensis and S. viscosus, a narrow endemic and a widespread ruderal

1993

The closely related Senecio nebrodensis, a perennial herb from four mountain ranges in Spain, and S. viscosus, an annual herb widespread in Europe, are being compared by the study of herbarium material and comparative cultivation. In cultivation, S. nebrodensis behaved as an annual, completing its life cycle within a shorter period of time than S. viscosus. The formation of basal leaf rosettes is much more pronounced in S. nebrodensis than in S.viscosus. The main difference between the two species, however, is their breeding system. While S. nebrodensis is self-incompatible, S. viscosus is self-compatible. Differences in reproductive morphology (mainly size and number of ray florets) are su…
